Start time, end time, and task tracker of individual tasks of a job
Jeff LI 2012-11-20, 16:13
Hello,

Is there a way to obtain the information of each individual task of a
map-reduce job, including start time, end time, which task tracker runs
this task and so on?

I know this information can be found through the web interface running on
the jobtracter.  But is it possible to redirect the information to a nicely
formatted log file for each job?

By the way, I'm running hadoop 0.20.2-cdh3u5.

Thanks advance for the help.

Cheers

Jeff
